This sample demonstrates the ease of integrating quality of service modules to the WSO2 Application Server by taking security and reliable messaging as examples. We investigate the interactions between a simple Web service client and a service ( CommodityQuote) . This "CommodityQuote" service provides information of chemical agents in the d-block of the periodic table.

You can find the "CommodityQuote" sample discussed here in <AS_HOME>/samples/CommodityQuote directory. This sample emulates a simple "stock trader", where you can get the stock symbols and the stock quote for a particular stock symbol. In this case, the stocks are elements in the periodic table, and stock symbols are the corresponding chemical element symbol.

The Scenario: "CommodityQuote" Service

The client queries the "CommodityQuote" service for available chemical elements (symbols). Using one of these symbols, the client gets stock quotes from the "CommodityQuote" service.

The "CommodityQuote" service offers the following to the client:

  • A list stock symbols
  • Stock quote and portfolio where the possible attributes of the stock quote are "name", "symbol", "selling price", "high price" and "low price."

How to Build and run the Sample

Find the "CommodityQuote" sample discussed here in <AS_HOME>/samples/CommodityQuote directory. You need Apache Ant to build the sample.

The steps are as follows:

1. Install and run the WSO2 Application Server. Refer to the  Installation Guide for instructions.

2. In a command prompt, switch to the CommodityQuote directory.

For example, cd AS_HOME\samples\CommodityQuote

3. From there, type ant .

4. The build resumes and should be completed successfully. 

5. The build automatically copies the .aar file containing the service into the repository. If you go to the Deployed Services window in the Application Serve Management Console, you will see the CommodityQuote service deployed. 

Note:
If you don't see the service deployed, wait for a while for the deployment engine of Axis2 to pick up the newly added .aar. Then refresh/reload the page.

6. To see the Deployed Services window sample service in action, you can use the following syntax on the command prompt.

  • On MS Windows: run-client.bat [ -qos (rm|secure|securerm)] [ -e CommodityQuoteServiceURL]
  • On Unix/Linux: run-client.sh [ -qos (rm|secure|securerm)] [ -e CommodityQuoteServiceURL] 

You can find the run-client.bat and run-client.sh files in the <AS_HOME>/samples/CommodityQuote directory.

Terms Used

-e : is the Endpoint Reference (EPR) of the "CommodityQuote" service. You can find the endpoints in the AS Management Console.

Go to the " Deployed Services" page and click on the service "CommondityQuote." This will open up its dashboard, where you can find its endpoints.  (under services column) > End Points. For this sample the default URLs for the standalone distribution and the embeddable version are as follows:

The default EPRs for http and https will be available in:

<AS_HOME>/samples/CommodityQuote/conf/default_epr.properties file.

In addition to this, the ssl connection ( https://127.0.0.1:9443/services/CommodityQuote or https://127.0.0.1:9443/wso2appserver/services/CommodityQuote ) is needed for security scenarios. This is discussed later.

-qos : This represents rm, secure or securerm options, which eventually engage respective modules to the "CommodityQuote" service. These modules can be easily engaged from the AS Management Console. To run the sample with these QoS functions, you must engage the respective module for the "CommodityQuote" service in the WSO2 Application Server.

Note:
Some of the sce narios listed above need provisioning for unlimited security jurisdiction. This is basically a couple of .Jar files, which are available at Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files here: http://www.oracle.com/technetwork/java/javase/downloads/index.html

Download jce_policy-x_y_z.zip (relevant to your JDK version) and extract the jar files local_policy.jar and US_export_policy.jar to $JAVA_HOME/jre/lib/security.

  • securerm - Both Sandesha2 and Rampart. securerm option demonstrates all the security scenarios with reliable messaging.

The options shown above are illustrated using the following samples.

Sample 1: Without any Module Engaged.

From the "CommodityQuote" directory, type the following command. $ ./run-client.sh. You should see the following:

STARTING COMMODITY QUOTE SAMPLE CLIENT
=============================

Sample will be invoked using following parameters ..
CommodityQuoteService Endpoint reference : http://127.0.0.1:9763/services/CommodityQuote

Please select your operation...
---------------------------------
(1) getQuote
(2) getSymbols
(3) Exit

Sample 2: With -qos Secure : Rampart/Rahas Modules Engaged.

From the "CommodityQuote" directory, type the following command. $ ./run-client.sh -qos secure. You should see the following:

STARTING COMMODITY QUOTE SAMPLE CLIENT
=============================

Enter security scenario 1 - 15...

Select a value between 1 to 15. Each scenario is described below from 1 to 15.

Value 1

Username Token authentication

  • Server Side:Login to the Application Server Management Console. 
    • Then add a user (under configure -> Users and Roles) named "bob" with password "password".
    • Similarly, add a role "testrole" and add user "bob" to that role.
    • Provide all permissions for this role.
    • Then go to the "Deployed Services" window in the AS Management Console. (Manage > Service > List).
    • Access the dashboard of the service "CommodityQuote" by clicking on it.
    • In the dashboard, under "Security," select "Username Token." Press "Next".
    • Then select "testrole" from the user groups listed.
    • Click "Finish".
  • Client Side: You should see the following.

Note: If you run into a timestamp validation issue when trying this using two machines for client and service, then the clocks of the two machines are off by more than 5 minutes(default max time skew allowed by Apache Rampart). If you need to increase this value, please edit the "RampartConfig/timestampMaxSkew" assertion using the policy editor.

Value 2

Non-repudiation requests and responses are signed for this scenario to work. The "CommodityQuote" service needs to import a certificate. Let this certificate be service.jks. In addition to this, the client needs to import the private key of the service.jks. Let's say this is client.jks. For this demonstration, service.jks and client.jks will be shipped with the sample and it's located at <AS_HOME>/samples/CommodityQuote/keys.

  • Server side :Login to the AS Management Console.
    • Access Keystores under the Configure menu.
    • Upload the service.jks. Keystore password is "testing" and private keystore password is "testing".
    • Then go to the "Deployed Services" window in the AS Management Console. (Manage > Service > List).
    • Access the dashboard of the service "CommodityQuote" by clicking on it.
    • In the dashboard, under "Security," select "Sign only"(Non Repudiation). Press "Next".
    • Select Trusted Certificate Stores as service.jks and private keystore as service.jks in the next page.
  • Client Side: You should see the following.
